The guide plate 6 is formed with an arcuate guide groove 8 corresponding to the application location of the adherend B shown in FIG.

Further, a movable member 9 driven by the air cylinder 5 is movably installed on the guide rail 7 . Therefore, the air cylinder 5 and the moving member 9 are connected via the piston rod 10, and the groove 12 of the sliding part 11 protrudes from both sides of the lower surface of the moving member 9, and the guiding protrusion 13 of the guide rail 7. and are engaged with each other as shown in FIG.

It is connected to a compressed air supply source (not shown) via. The converter unit 14 is a type of hydraulic damper,
While keeping the operating speed of the air cylinder 5 constant,
It also has the effect of varying the coating speed.

On the other hand, a base 20 of an arm 19 is connected to the rear side of the moving member 9 via a link mechanism 18.

The link mechanism 18 comprises two connecting members 21.22, a moving member 9, two connecting members 21.22 and an arm 19.
The four members of the base 20 constitute a four-bar parallel link. Therefore, the connecting member 21.22 is connected to the rotating wheel 23.2.
4 respectively the rear part of the moving member 9 and the arm 19
It is pivoted to the base 20 of. In addition, - connection member 22
As shown in FIGS. 2 and 3, protrusions 22a and 22b facing each other are integrally formed, and the upper protrusion 22
a is connected to the base 20 of the arm 19 as described above, and a bracket 25 is fixed to the lower part of the lower protrusion 22b. At the bottom of the bracket 25, a rotating roller 26 that engages with the guide groove 8 of the guide plate 6 is attached to a pin 27 located coaxially with the rotating shaft 24.

The arm 19 is erected on the connecting member 21.22, and its upper end is bent in a substantially horizontal direction.

At the tip of the bent portion 2 of this arm 19, an opening/closing valve 29, a spout nozzle 30, and a coating rod 31, which are adhesive coating means, are housed in a direction substantially perpendicular thereto. The opening/closing valve 29 is configured to be opened/closed by control air pumped through the hose 32. Further, the jet nozzle 30 is supplied with a highly adhesive adhesive that is pumped through a hose 33 from an adhesive supply pump (not shown).

In addition, 34 is a kicker, and 35 is a limit switch, and the adhesive application operation of this apparatus is controlled by these kicker 34 and limit switch 35.

In order to apply adhesive to an object B, for example, a corner of the lower edge of a door frame opening of a side body of a car, using the adhesive applicator configured as described above, the object B is first applied by the conveying device C. Transport it to the position corresponding to the device. During this time, the support base 2 is rotated upward by the jack 3 and tilted, so that the coating rod 31 attached to the arm 19 does not come into contact with the object B.

Next, the support base 2 is rotated downward by the jack 3, and the rod 31 is inserted into the opening of the transported object B and comes into contact with the arc-shaped corner coating surface. I am made to do so. The adhesive supplied to the nozzle 30 through the hose 33 flows out from the nozzle 30 and is transmitted to the rod 31.

At the same time, the air cylinder 5 is activated, the piston rod IO is retracted, and the moving member 10 is moved forward (to the left in the figure). Along with this, the rotating roller 26 moves along the guide groove 8 having the same shape as the coating surface, so the rod 31 also moves along the same trajectory as the guide groove 8 via the link mechanism 18 and the arm 19. (see Figure 4),
As a result, the adhesive is evenly applied to the application surface of the object B.

When the above coating operation is completed, the support base 2 is rotated upward by the jack 3, and the rod 31 is pulled up from the opening of the object B. Thereafter, the object to be adhered B is transported by the transport device C to the next step.

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and various modifications and changes can be made based on the technical idea of the present invention.

For example, in the embodiments described above, the guide groove 8 is formed in a downward arc shape, but it is also possible to form it in an opposite arc shape or other shape in accordance with the coating surface of the object B. .

d. Effects of the Invention As described above, the adhesive applicator according to the present invention has a driving means and a guide plate arranged in relation to each other on the top surface of a tiltable base, and is moved by the driving means when applying adhesive. A guide groove of a guide plate, in which the member is moved and a link mechanism connected to the moving member is actuated, and the arm to which the adhesive application means is attached is formed in a shape corresponding to the application location of the object to be adhered. Since the adhesive is configured to move along the surface of the adhesive, it is possible to quickly and evenly apply the adhesive to the application surface of the object to be adhered.
Compared to conventional automatic coating equipment, the structure is simpler and can be manufactured at a lower cost, reducing equipment costs.

Further, since the coating device of the present invention is elongated from front to back, it can be installed in a small space on the line side when used, for example, for applying sealer to the side body of an automobile, and the space can be used effectively.
